The goal of this project was to build a tool that could be used to predict how long Old Faithful was going to erupt based on the length of waiting time.
Figure 1: Old Faithful erupts in front of a throng of tourists
Waiting time between eruptions and the duration of the eruption for the Old Faithful geyser in Yellowstone National Park, Wyoming, USA.
Figure 2: Old Faithful with the Milky Way overhead.
As we can see below a linear model is a fairly accurate predictor of eruption time.
The model summary output from can be seen below.
